So the question is, is this a dirt bike? Well if you take the big GS off-road, then yes it is. It isn't anything you'd be looking to go tackle tough trails on, it is more of a gravel or jeep road explorer where when the speeds are kept under control, it will perform better than expected. Today alone we rode in mud, snow, ice, pavement, wood bridges, water crossings, got turned around on CHP closed roads, more snow and ice and some fine trails between great lunch and rest stops, which BMW is famous for finding. But forget what the bike is, a full-fledged touring bike you could ride around the world, and the bottoming of the suspension and heavy weight has to be excused. Power is never an issue. The best thing about a flat twin is the gratuitous torque and smooth power it pumps out. The GSA has a low enough first gear to get the work done in creeping across tough stuff without killing the clutch as long as you don't rev the engine and slip it a lot. It is a ride-it-all-day through whatever the conditions present you with and make it back to the bar to have a Kessler or Pabst, your choice, if that is your thing (or they serve that stuff!)There is almost a cult of adventure riders out there for whom the GS is the bike of choice. It has a history that attracts them, a performance level, albeit a bit different than the norm, that they fall in love with and a accessory addiction that is well fed with every type of gadget, protection, gismo and luggage known to man. It would make a Harley rider jealous.
